Intelligent reflecting surfaces enable accurate 3D multi-target localization in wireless networks.
Abstract
This paper explores a novel 3D multi-target localization system using intelligent reflecting surfaces (IRS) in wireless networks. The study focuses on single-target and multi-target cases, proposing localization protocols and algorithms. By controlling the on/off state of IRS, the system achieves sub-meter-level positioning accuracy. Key insights include:
Introduction to environment-aware applications in wireless networks.
Challenges faced by traditional cellular base stations for sensing.
The role of intelligent reflecting surfaces in enhancing sensing capabilities.
Two-stage localization protocol for single-target cases.
Extension to multi-target localization with adaptive sensing protocols.
Simulation results demonstrating the effectiveness of the proposed scheme.
